Ya know what's happened?
Up 99-91 with 3 minutes left, the Celtics thought the Bulls were gonna waive the white flag so they decided to half-ass their play. Well it came back to bite them and now they're flustered.
It's almost like they're in shock that they're in overtime right now and don't really know how to react and so their offense is stuttering.
And now with Baby in and Perk out, it seems like Doc is panicing on his substitutions
